How can I manage stress positively

1.Stepping back from the situation
When you feel yourself becoming tense in a situation try stepping back from it and observe how you are reacting.
2.Better breathing
When we become anxious and tense our breathing changes. It becomes shallow, fast and irregular.Breath about 3secs until you become calmer.
3.Relax
clench each set of muscles tightly so you can feel all the tension being concentrated in that one place then release the tension letting it flow out of your body.
4.Easy eating
Try to eat slowly and peacefully and enjoy your meal. If you are feeling stressed you could consider vitamin supplements.
5.Don't try to be perfect
Think about what is important to you, what you want to focus on, what you want to achieve rather than trying to live up to other people's expectations.
